Raptoxx RT-EBAD1200 Exxtreme 1200W PSU review

Page 4 - Testing methods and results

The computer we tested Raptoxx EBAD-RT1200 1200W with was the best we had at the time, while at same time being one of the most powerful machines you could obtain nowadays.

• Motherboard: DFI LanParty DARK 790FXB-M2RSH
• CPU: AMD Phenom II (Deneb core) 940 Black Edition 3GHz
• Video cards: 2 x Sapphire HD4870X2 2GB in CrossFireX mode
• Memory: 2 x 2GB A-Data DDR800
• Hard drive 1: Western Digital Velocity Raptor 10 000 RPM 150GB
• Hard drive 2: Seagate Barracuda 7200.11 7200RPM 300GB
• Optical drive: ASUS DVD+/-RW LightScribe 20x
• Cooling: 2 x 200mm fans, 2 x 120mm fans, 1 x 140mm fan

PSU's for comparison

• Corsair TX750W
• NOX APEX 700W
• Silver Power SP-SS500 500W

Tests for PSU voltages in idle and under load modes were made with the above mentioned configuration. Later we decided to run tests for energy efficiency with few more PSU's, in which test we would measure the amount of power consumed from the system while performing the exactly same operations with the exactly same hardware but with different PSU. That would show with great preciseness the difference in effectiveness of the few "80+" models that were in the ModReactor lab.

For the tests we used a good multimeter. We measured the power consumed with a plain home Power Meter, that can be obtained anywhere for about 12$ - 20$ and has accuracy of +/- 1W, which is quite acceptable. The tests for Raptoxx RT-EBAD1200 were concluded with the above mentioned machine, but the tests for all other PSU's were concluded with ONLY ONE Sapphire HD4870X2, which lowers the power consumption of the system with up to 200W.

We were astonished from the perfect voltages of Raptoxx RT-EBAD1200! No fluctuations whatsoever even when changing from heavy load mode to low load mode. That situation does heavily load the 12V lines of the PSU. Most cheap models compensate that by lowering the voltage at the 5V line while the 12V will still "feel" it an will fluctuate. Yes, we did load the PSU only at 60% of its declared maximum, but the results clearly convince us that at the declared full maximum it will still perform flawlessly.

Next we did the tests for energy efficiency. For them all PSU's were concluded with ONLY ONE Sapphire HD4870X2, which lowers the power consumption of the system with up to 200W.

The Raptoxx PSU proved to be the most power efficient one. Although the load is negligible compared to its full capability it still goes to show that the company had made sure that their product treats fine both the environment and your power bill :)
